The Shadow of a Shadow: A Proposed Geometric Derivation of α = 1/137 from Projection Geometry — ULF Paper XXV

Revised edition of Paper XXV. Proposes a geometric derivation of the fine structure constant α = √3/24π² within the Unified Light Framework, giving 1/α = 136.76 against the measured 137.036 — agreement of 0.20%. Two corrections from the original: the claim of being the first derivation in history is removed — prior attempts by Wyler (1969) and others are acknowledged. A genuine inconsistency between the √3/24π² route and the Γ²/36 route is identified and left honestly open. A genuine testable prediction is highlighted: the ULF value should fall within the QED running of α at the Planck scale. Proposed framework — not proven theory.
